Taylor R-0007-E Thiosulfate Reagent – 0.75 oz Refill (Chlorine Neutralizer for TA Tests)
The Taylor R-0007-E is a replacement bottle of Thiosulfate Reagent used as a chlorine neutralizer in several Taylor water tests—most commonly the Total Alkalinity (TA) drop-count test. It helps prevent high sanitizer levels from interfering with the indicator color change, improving accuracy when testing pools that have recently been shocked or run at higher chlorine.
Key Features
- Neutralizes chlorine/bromine in the sample to reduce test interference
- Commonly used in the Total Alkalinity test before adding the TA indicator and titrant
- Helps improve accuracy when sanitizer levels are elevated
- Convenient refill size for topping off frequently used test kits
How It’s Used (Overview)
- Add the recommended drops of R-0007 to the measured sample (per your Taylor kit instructions).
- Continue the test procedure by adding the appropriate buffer/indicator and titrating as directed.
- This step is especially useful when chlorine is high or the sample color is being “bleached” by sanitizer.
